Abstract:
|
Dynamics of resonant energy transfer of a single excitation in a molecular dimer system are studied in
the simultaneous presence of diagonal and off-diagonal exciton-phonon coupling. It is found that, at
given temperatures, the off-diagonal coupling can enhance both the coherence of the resonant energy
transfer and the net quantity of energy transferred from an initially excited monomer to the other. Also
studied is the dynamics of entanglement between the dimer system and the phonon bath as measured
by the von Neumann entanglement entropy, and the inter-monomer entanglement dynamics for the
excitonic system. |
